Widget description

The progress bar is a widget for visually representing the progress status of a given job/task.

A progress bar may be horizontal or vertical. It may display an icon besides it, as well as primary and units labels. The former is meant to label the widget as a whole, while the latter, which is formatted with floating point values (and thus accepts a printf-style format string, like "%1.2f units"), is meant to label the widget’s progress value. Label, icon and unit strings/objects are optional for progress bars.

A progress bar may be inverted, in which case it gets its values inverted, i.e., high values being on the left or top and low values on the right or bottom, for horizontal and vertical modes respectively.

The span of the progress, as set by span_size, is its length (horizontally or vertically), unless one puts size hints on the widget to expand on desired directions, by any container. That length will be scaled by the object or applications scaling factor. Applications can query the progress bar for its value with value.

This widget emits the following signals, besides the ones sent from LayoutClass:

  • changed - when the value is changed
